This presentation expounds the most important thing about cryptocurrencies. After you have read it, you‘ll realize more about it than most other people.

nowadays cryptocurrencies became a global event known to most humans in the world. While still somehow geeky and not comprehend by most humans, banks, governments and many companies are knowing its value.

In the last two year, you had a hard time to find a great bank, a big accounting foundation, a featured software corporation or a ministry that did not research cryptocurrencies.

But let’s be away from the commotion and the press releases, the most people – even engineers, operators, consultants, and scientists – have a limited knowledge and short vision about cryptocurrencies. The most time fail to even realize the basic concepts.

So let‘s take a story from the beginning. What are cryptocurrencies?

  • Why you have to learn about cryptocurrency?
  • Where did cryptocurrency begin?
  • What do you want to know about cryptocurrency?

What is cryptocurrency, and how cryptocurrencies grow as a side product of digital money?

Rare humans know that, but cryptocurrencies began as a side product of another discovery. Satoshi Nakamoto, the anonymous that who discovered Bitcoin, the first and most famous and powerful cryptocurrency in the world, never planned to create a currency.

In his declaration of Bitcoin in 2008, Satoshi said he created “A Peer-to-Peer Electronic Cash System.“

His purpose was to create something; a lot of people failed to develop before digital cash.

Announcing the first release of Bitcoin, a new electronic cash system that uses a peer-to-peer network to prevent double-spending. It’s completely decentralized with no server or central authority.  – Satoshi Nakamoto, 09 January 2009, announcing Bitcoin on SourceForge.

The only important part of Satoshi‘s discovery was that he found a way to develop a decentralized digital cash system. In the nineties period, there have been a lot of trials to innovate digital cash, but they all failed.

   after more than a decade of failed Trusted Third Party based systems (Digicash, etc), they see it as a lost cause. I hope they can make the distinction, that this is the first time I know of that we’re trying a non-trust based system. – Satoshi Nakamoto in an E-Mail to Dustin Trammell

Then when all the centralized attempts failed, Satoshi decided to develop a digital cash system without a central authority. Like a Peer-to-Peer network for file distribution.

So, Satoshi’s decision became the cryptocurrency birth. They are the lost part Satoshi found to recognize digital cash. The reason is a little complex and technical, but if you understand it, you will realize more about cryptocurrencies than majority humans do.

So, let‘s make it as simple as convenient:

How to recognize a digital cash? To recognize a digital money you require a payment network with account, balance, and transaction. That‘s simple to comprehend. There is one main problem each payment network has to fix is to block the so-called double spend: to stop that one entity expends the same amount twice. Ordinarily, this is done by a central server who save a record of the balances.

In a decentralized network, you don‘t have this server. So you need each individual entity of the network to do this job. The network peers, each one from them needs to have a list including all activities and transactions to check if the transactions in the future are valid or a trying to double spends.

But how these entities can retain an agreement about this records?

If the peers of the network conflict about just one single minor balance, everything is split. They must reach a full agreement. Regularly, you take, again, a central authority to announce the valid state of balances. But how you can achieve a full agreement without a central authority?

Noone did believe that until Satoshi appeared out of nowhere. In fact, none believed it was possible.

Satoshi shows evidence that it was. His major discovery was to achieve an agreement without a central authority. Cryptocurrencies are a piece of this solution – the piece that made the solution exciting, interesting and helped it to move a world forward.

What are cryptocurrencies actually?

If you cut all the yelling about cryptocurrencies and reduce it to an uncomplicated explanation, you observe it to be just limited entrances in a database nobody can edit without accomplishing particular conditions. This may seem normal, but, believe that or not: this is completely how you can determine a currency.

Take the cash on your bank account: What is it more than entrances in a database that must be changed under particular conditions? You can also get physical coins and observances: What are they else than restricted entrances in an open physical database that must be changed on the off chance that you suit the condition than you physically keep the coins and notes? Cash is about a checked entrance in some sort of database of accounts, exchange, and balances.

How miners generate cryptocurrency and confirm transactions?

Let‘s take a look at the mechanism ruling the databases of cryptocurrencies. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.

How about we investigate the component administering the databases of cryptocurrencies forms of money. A cryptocurrency like Bitcoin comprises a system of asso nn ciates. Each companion has a record of the entire history everything being equal and in this way of the adjust of each record.

A transaction is a file that says, “Bob gives X Bitcoin to Alice“ and is signed by Bob‘s private key. It‘s basic public key cryptography, nothing special at all. After signed, a transaction is broadcasted in the network, sent from one peer to every other peer. This is basic p2p-technology. Nothing special at all, again.

An exchange is a record that says, “Bounce gives X Bitcoin to Alice” and is marked by Bob’s private key. It’s fundamental open key cryptography, nothing unique by any stretch of the imagination. After marked, an exchange is communicated in the system, sent from one associate to each other companion. This is essential p2p-innovation. Nothing exceptional by any stretch of the imagination, once more.

The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed.

Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation.

As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone. It is no longer forgeable, it can‘t be reversed, it is part of an immutable record of historical transactions: of the so-called blockchain.

Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain.

For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins. Since the miner‘s activity is the single most important part of cryptocurrency-system we should stay for a moment and take a deeper look on it.


What are miners doing?


Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately.

So, Satoshi set the rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash – a product of a cryptographic function – that connects the new block with its predecessor. This is called the Proof-of-Work. In Bitcoin, it is based on the SHA 256 Hash algorithm.

You don‘t need to understand details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.

Bitcoins can only be created if miners solve a cryptographic puzzle. Since the difficulty of this puzzle increases the amount of computer power the whole miner’s invest, there is only a specific amount of cryptocurrency token that can be created in a given amount of time. This is part of the consensus no peer in the network can break.


Revolutionary properties


If you really think about it, Bitcoin, as a decentralized network of peers which keep a consensus about accounts and balances, is more a currency than the numbers you see in your bank account. What are these numbers more than entries in a database – a database which can be changed by people you don‘t see and by rules you don‘t know?

Basically, cryptocurrencies are entries about token in decentralized consensus-databases. They are called Cryptocurrencies because the consensus-keeping process is secured by strong cryptography. Cryptocurrencies are built on cryptography. They are not secured by people or by trust, but by math. It is more probable that an asteroid falls on your house than that a bitcoin address is compromised.

Describing the properties of cryptocurrencies we need to separate between transactional and monetary properties. While most cryptocurrencies share a common set of properties, they are not carved in stone.


Transactional properties:


1.) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

2.) Pseudonymous: Neither transactions nor accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real world identity of users with those addresses.

3.) Fast and global: Transaction is propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesn‘t matter if I send Bitcoin to my neighbour or to someone on the other side of the world.

4.) Secure: Cryptocurrency funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers makes it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.

5.) Permissionless: You don‘t have to ask anybody to use cryptocurrency. It‘s just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.


Transactional Properties:

1.) Controlled supply: Most cryptocurrencies limit the supply of the tokens. In Bitcoin, the supply decreases in time and will reach its final number somewhere in around 2140. All cryptocurrencies control the supply of the token by a schedule written in the code. This means the supply of a cryptocurrency in every given moment in the future can roughly be calculated today. There is no surprise.

2.) No debt but bearer: The Fiat-money on your bank account is created by debt, and the numbers, you see on your ledger represent nothing but debts. It‘s a system of IOU. Cryptocurrencies don‘t represent debts. They just represent themselves. They are money as hard as coins of gold.

To understand the progressive effect of cryptocurrency you have to think about the two properties. Bitcoin as a permissionless, irreversible and pseudonymous method for payments is an assault on the control of banks and governments over the financial transactions of their nationals. You can’t prevent somebody to use Bitcoin, you can’t deny somebody to acknowledge an payment, you can’t undo a transaction.

As money with a restricted, controlled supply that isn’t variable by a legislature, a bank or some other central authority, cryptocurrency assault the extent of the financial policy. They take away the control national banks go up against inflation or deflation by controlling the money related supply.

Cryptocurrency: Dawn new economy

Generally because of its progressive properties cryptocurrency have turned into a win their designer, Satoshi Nakamoto, didn’t aim to hope for it. While many others try to make an advanced money system didn’t pull in a minimum amount of clients, Bitcoin had something that incited eagerness and interest. Here and there it feels more like religion than innovation.

cryptocurrency is a digital gold. Sound cash that is secure from political force. Cash that guarantees to protect and increment its incentive after some time. Cryptocurrency is additionally quick and agreeable methods for payment with an overall degree, and they are private and sufficiently mysterious to fill in as a method for payment for bootleg trades and some other banned monetary movement.

Be that as it may, while digital currencies are more utilized for payment, its utilization as a method for hypothesis and a store of significant worth diminutive people the payment perspectives. Cryptocurrency brought forth an inconceivably powerful, quickly developing business sector for financial specialists and theorists. Trades like Okcoin, poloniex or shapeshift empowers the exchange of several cryptographic forms of money. Their day by day exchange volume surpasses that of real European stock trades.

In the meantime, the praxis of Initial Coin Distribution (ICO), for the most part, encouraged by Ethereum’s smart contracts, offered live to staggeringly fruitful crowdfunding investments, in which regularly a thought is sufficient to gather a huge number of dollars. On account of “The DAO” it has been in excess of 150 million dollars.

In this rich biological system of coins and token, you encounter outrageous instability. Usually, a coin picks up 10 percent daily – now and then 100 percent – just to lose the same at the following day. On the off chance that you are fortunate, your coin’s esteem grows up to 1000 percent in maybe a couple weeks.

While Bitcoin stays by a long shot the most well known cryptographic money and most different digital forms of money have zero non-theoretical effect, financial specialists and clients should watch out for a few digital forms of money. Here we display the most famous digital currencies of today.

The unrivaled, the first and most popular Cryptocurrency. Bitcoin fills in as an advanced best quality level in the entire cryptocurrency industry, is utilized as worldwide methods for payment and is the accepted cash of digital wrongdoing like darknet markets or ransomware. Following seven years in presence, Bitcoin’s cost has expanded from zero to in excess of 650 Dollar, and its exchange volume achieved in excess of 200.000 every day exchanges.

There isn’t much more to say: Bitcoin is here to stay.


The brainchild of youthful crypto-virtuoso Vitalik Buterin has climbed to the second place in the chain of the importance of cryptocurrency. Other than Bitcoin its blockchain does not just approve an arrangement of records and equalizations yet of supposed states. This implies Ethereum can process exchanges as well as process contracts and projects.

This adaptability makes Ethereum the ideal instrument for blockchain – application. However, it includes some significant downfalls. After the Hack of the DAO – an Ethereum based shrewd contract – the engineers chose to complete a hard fork without an accord, which brought about the rise of Ethereum Classic. Other than this, there are a few clones of Ethereum, and Ethereum itself is a large group of a few Tokens like DigixDAO and Augur. This makes Ethereum more a group of digital forms of money than a solitary cash.


Perhaps the less prevalent – or most abhorred – venture in the digital currency network is Ripple. While Ripple has a local digital money – XRP – it is more about a system to process IOUs than a cryptocurrency itself. XRP, the money, doesn’t fill in as a medium to store and trade esteem, however more as a token to ensure the system against spam.

Ripple Labs made each XRP-token, the organization running the Ripple arrange, and is conveyed by them on will. Therefore, Ripple is frequently called pre-mined in the network and dissed as no genuine digital currency, and XRP isn’t considered as a decent store of significant worth.

Banks, in any case, appear to like Ripple. At any rate they embrace the framework with an expanding pace.


Litecoin was one of the principal cryptocurrency after Bitcoin and labeled as the silver to the advanced gold bitcoin. Quicker than bitcoin, with a bigger measure of token and another mining calculation, Litecoin was a genuine advancement, splendidly custom fitted to be the littler sibling of bitcoin. “It encouraged the rise of a few different digital forms of money which utilized its codebase yet made it, significantly more, lighter”. Illustrations are Dogecoin or Feathercoin.

While Litecoin neglected to locate a genuine use case and lost its second place after bitcoin, it is still effectively created and exchanged and is stored as a back up if Bitcoin failed.


Monero is the most conspicuous case of the cryptonite algorithm. This calculation was imagined to include the security highlights Bitcoin is missing. On the off chance that you utilize Bitcoin, each exchange is reported in the blockchain and the trail of exchanges can be taken after. With the presentation of an idea called ring-marks, the cryptonite calculation could slice through that trail.

The main usage of cryptonite, Bytecoin, was vigorously pre mined and along these lines dismissed by the network. Monero was the main non-premined clone of bytecoin and raised a considerable measure of mindfulness. There are a few different manifestations of cryptonote with their own little upgrades, yet none of it did ever accomplish an equal prominence from Monero.

Monero’s ubiquity topped in summer 2016 when some darknet markets chose to support it as a money. This brought about a consistent increment in the cost, while the genuine use of Monero appears to remain disappointingly little.

Other than those, there are many digital forms of money of a few families. A large portion of them are just endeavors to achieve financial specialists and rapidly profit, however a great deal of them guarantee play areas to test developments in digital money innovation.

What is the future of Cryptocurrency?

The market for cryptocurrency is quick and wild. Consistently new cryptocurrency develop, old kick the bucket, early adopters get well off and financial specialists lose cash. Each digital money accompanies a guarantee, for the most part an issue on everyone’s mind to turn the world around. Scarcely any survive the main months, and most are pumped and dumped by theorists and live on as zombie coins until the last bagholder loses trust ever to see an arrival on his speculation.

Markets are messy. However, this doesn’t change the way that digital currencies are staying put – and here to change the world. This is as of now happening. Individuals everywhere throughout the world buy Bitcoin to secure themselves against the degrading of their national cash. For the most part in Asia, a striking business sector for Bitcoin settlement has developed, and the Bitcoin utilizing darknets of cybercrime are prospering. An ever increasing number of organizations find the intensity of Smart Contracts or token on Ethereum, the primary certifiable use of blockchain advancements rise.

The insurgency is as of now happening. Institutional financial specialists begin to buy cryptocurrency. Banks and governments understand that this creation can possibly draw their control away. Cryptocurrency change the world. Well ordered. You can either remain close to and watch – or you can turn out to be a piece of history really taking shape.
